Filed: 1927-12-14
Abstract: 282,405. Tastenhoye, H., and Tastenhoye, F. Dec, 15, 1926, [Convention date]. Pressure gauges. -A device for signalling decrease of pressure in a closed vessel, shown for use in indicating deflation of a pneumatic tyre, comprises a whistle which is moved by means of a spring from inoperative to operative position (Figs. 2 and 1 respectively) when the pressure falls below a predetermined limit. The device comprises a tubular branch 1, for attachment to the valve stem of a tyre, fitted with a rubber &c. collar 8 for opening the valve to admit air from the tyre to a chamber 5. A diaphragm 7 in the chamber 5 bears against a disc 74 having a domed apertured head 71 which is normally pressed against a sleeve 101 carrying the whistle 10 to hold the latter inoperative against the pressure of a spring 103. The diaphragm 7 is clamped over the flanged outlet from the branch 1 in the mouth of which a movable disc 6 and a tightlyfitting ring 54 are mounted as shown. Projecting through the disc 6 is a soft rubber cone 62 with a stem 63 guided in th edisc 74. When the pressure in the tyre (and chamber 5) falls below the predetermined limit, the pressure of the spring 103 overcomes that of the head 71 on the sleeve 101 and the whistle is projected from the position shown in Fig. 1 to that shown in Fig. 2. The sleeve 101 is formed with a notch 102 to permit the head 71 to enter the casing 9, the movement of the disc 74 causing air to pass from the tyre through the whistle.

When the primary element is turned by a handle 30 the secondary element rotates with it, but when the latter is turned by a handle 35, the primary element is held against rotation by frictional engagement with elastomeric seals 5, 6 which may be spring- loaded. The member 9 is in screw-threaded engagement with a hollow spindle 10, and a pin 12 or adhesive is used to secure the screw threads; a further pin 31 limits angular rotation of the member 9. In modified constructions, the secondary element is screw-threaded for adjustment axially to regulate the volume of flow, may be rotated by a spanner and be locked in adjusted position by a nut (38), Fig. 4 (not shown), or may be integral with a cover (26), Fig. 5 (not shown), for the valve body. In a further modification, the primary element controls the volume and the secondary element the temperature, the elements having cooperating ports (20, 21), Figs. 6 and 7 (not shown), in their cylindrical walls to adjust the ratio of hot to cold flow. The secondary element may also be designed to be pre-set by a screwdriver inserted into a slot (35), Fig. 8 (not shown). Fig. 12 shows a valve in which the ratio of hot and cold flows from inlets 2 (only one of which is shown) is varied by rotating a primary element 9 with a handle 30 while flow through an outlet 4 is adjusted by turning a handle 26 to displace the element 9 axially. In further embodiments a single lever (63), Figs. 14 and 15 (not shown), is used to turn the primary element and to axially displace the secondary element.

Title: Improvements in or relating to data storage apparatus
IPC: G06F3/00
Filed: 1964-08-21
Abstract: 1,021,906. Electric digital data-storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 21, 1964 [Aug. 21, 1963], No. 34329/64. Heading G4C. A data-storage system has the following two modes of operation, which are claimed separately: (a) if data is detected in a predetermined time-sector of first storage means 15 (Fig. 1, not shown) it is gated to an input to the first storage means, otherwise data from an external source is gated to the input; (b) data passes through first and second storage means 15, 22 (Fig. 1, not shown) in turn and if it is requested while passing through the second, it is gated to an external receiver, whereas otherwise it is gated to the input to the first storage means. In Fig. 1 (not shown) the first store (magnetic drum, disc, or tape) stores records consisting of 2-out-of-5-coded characters, the distance between write and read heads holding an integral number of records minus one character. The second store introduces a one-character delay between its input and output. At the beginning of each character time, two clock pulses Ta, Tb (not shown) in that order are applied to the system.  For the first mode of operation, a switch 25, 26, 27 (not shown) is in its first position. At the beginning of a character time, a control trigger is reset by clock pulse Tb (not shown). Then any data present in that character time from the read head passes to the second store and also sets the control trigger so the clock pulse Ta (not shown) at the beginning of the next character time sets a revolve trigger. This gates the data, now emerging from the second store, through a revolve gate to the write head. If no data was present during the first character time, the control trigger would not be set and clock pulse Ta (not shown) would reset (or leave reset) the revolve trigger which would gate data from an input buffer register to the write head.  For the second mode of operation, the switch is in its second position. Clock pulse Tb (not shown) sets the control trigger and unless a data request signal is received, data from the read head is passed through the revolve gate to be re-written in the first store. On the other hand, if a data request signal is received while data from the read head is in the second store, then the control trigger is reset and the next Ta (not shown) clock pulse resets the revolve trigger to enable a transmit gate, thereby passing the data to an external receiver. Fig. 3 (not shown) shows a modification in which the revolve trigger is replaced by a singleshot. Fig. 5 (not shown) shows a modification in which the second store is dispensed with by having two read heads on the first store, one character time apart. One head feeds the revolve and transmit gates and the other feeds the control trigger. It is mentioned that the read and write amplifiers may synchronize data signals passing through, that erasure means for the first store may be provided; and that the first store may alternatively be sequentially-addressed cores or a delay line.
